This research argues that immigrants political, social, and economic incorporation experiences, which are embedded in individual life course trajectories and heavily influenced by governmental policies, play an important role in producing diverse health outcomes among older U.S. foreign-born persons. Using data from the 2008-2010 American Community Survey and 1998-2010 Integrated Health Interview Series, we demonstrate how naturalization, a key indicator of social and political inclusion, is related to functional health in midlife and older age. Consistent with the theoretical framework, we find that among those foreign-born who immigrated as children and young adults, naturalized citizens show better health at older ages compared with noncitizens, although this relationship is partly mediated by education. But among those older foreign-born who immigrated at middle and older ages, naturalized citizens report worse health compared with noncitizens. Moreover, this negative health selection into naturalization becomes stronger for those naturalizing after the 1996 Welfare Reform Act.

This research projects the racial and ethnic composition of the U.S. population over the next 3 decades, and finds that it is rapidly changing in response to decades of sustained large-scale immigration.

Undocumented status is widely recognized as an important social determinant of health. While undocumented immigrants have lower levels of health care access, they do not have consistently poorer physical health than the US-born or other immigrant groups. Furthermore, heterogeneity by race/ethnicity has been largely ignored in this growing literature. This paper used the 2001, 2004, 2008 panels of the restricted Survey of Income and Program Participation (SIPP), one of the only representative surveys equipped to adequately identify Asian undocumented immigrants, to compare health patterns between Asians and Latinos by immigration status. We examined three general measures of health/health access: self-rated health, disability, and current health insurance. Latino undocumented immigrants displayed some advantages in self-rated health and disability but had lower insurance coverage compared to US-born Latinos. In contrast, Asian undocumented immigrants did not differ from US-born Asians in any of the three outcomes. While undocumented status has been proposed as a fundamental cause of disease, we found no evidence that Latino and Asian undocumented immigrants consistently fare worse in health access or physical health outcomes than immigrants in other status categories. Different racial groups also appeared to have unique patterns between immigration status and health outcomes from one another.

The accuracy of counts of U.S. racial/ethnic and immigrant groups depends on the coverage of the foreign-born in official data. Because Mexicans constitute by far the largest single national-origin group among the foreign-born in the United States, we compile new evidence about the coverage of the Mexican-born population in the 2000 census and 2001-2010 American Community Survey (ACS) using three techniques: a death registration, a birth registration, and a net migration method. For the late 1990s and first half of the 2000-2010 decade, results indicate that coverage error was somewhat higher than currently assumed but had substantially declined by the latter half of the 2000-2010 decade. Additionally, we find evidence that U.S. census and ACS data miss substantial numbers of children of Mexican immigrants, as well as people who are most likely to be unauthorized: namely, working-aged Mexican immigrants (ages 15-64), especially males. The findings highlight the heterogeneity of the Mexican foreign-born population and the ways in which migration dynamics may affect population coverage.
